Line-winding device, fishing reel, and winch

Abstract

A line-winding device including a tension detection unit that can be incorporated in a reel, can be downsized, and can measure a tension with high accuracy even at the time of stopping without the need to bend a line path. A line-winding device is configured to include: a spool capable of winding a fishing line; an operating part for winding the fishing line around the spool; a support shaft portion for rotatably supporting the spool; a restoring force generation unit for generating a restoring force between the support shaft portion and the spool; a restricting part for restricting a rotational movement amount of the spool; and a detection unit for detecting the rotational movement amount of the spool.

1 . A line-winding device comprising: a spool capable of winding a fishing line; an operating part for winding the fishing line around the spool; a support shaft portion for rotatably supporting the spool; a restoring force generation unit for generating a restoring force between the support shaft portion and the spool; a restricting part for restricting a rotational movement amount of the spool; and a detection unit for detecting the rotational movement amount of the spool. 
     
     
         2 . The line-winding device according to  claim 1 , comprising: a fishing line diameter detection unit for detecting a diameter of the fishing line wound around the spool; and a tension calculation unit for calculating a tension from the diameter of the fishing line and the rotational movement amount of the spool. 
     
     
         3 .
